DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0019] like Figure 1 As shown, this embodiment provides a cylindrical precision parts clamping tool, including a carrier plate 1 and a clamping mechanism 2.

[0022] During operation, the cylindrical precision part is coaxially placed on the carrier plate 1, and the clamping mechanism 2 is radially moved along the carrier plate 1 so that the rotating column 22 contacts the outer surface of the cylindrical precision part and squeezes it to fix it; the carrier plate 1 is rotated to adjust the angle between the cylindrical precision part and the placement surface of the clamping tooling so that the cylindrical precision part is at a suitable processing angle; the clamping mechanism 2 is axially moved along the carrier plate 1 so that the clamping mechanism 2 drives the cylindrical precision part to move axially, and then adjusts the distance between the cylindrical precision part and the carrier plate 1 to avoid the cylindrical precision part being blocked by the carrier plate 1 during processing because it is too close to the carrier plate 1; the rotating column 22 is rotated so that the rotating column 22 drives the cylindrical precision part to rotate around its own central axis so that all positions on the outer surface of the cylindrical precision part can be processed.

[0023] Preferably, Figure 1 and Figure 2 As shown, the carrier plate 1 is provided with sliding grooves 11 whose number matches the clamping mechanism 2. Specifically, in this example, three sliding grooves 11 are provided; a first linear mechanism 12 is provided in the sliding groove 11 along the radial direction of the carrier plate 1, and the first linear mechanism 12 can adopt a linear drive mechanical device such as an electric screw; the first linear mechanism 12 is matched with a sliding seat 13, and a second linear mechanism 14 is provided on the sliding seat 13 along the axial direction of the carrier plate 1, and the second linear mechanism 14 can adopt a linear drive mechanical device such as an electric screw; the rotating seat 21 is matched with the second linear mechanism 14, the first linear mechanism 12 is used to drive the clamping mechanism 2 to move radially along the carrier plate 1 through the sliding seat 13, and the second linear mechanism 14 is used to drive the clamping mechanism 2 to move axially along the carrier plate 1.

[0024] Preferably, Figure 2 As shown, a first rotating mechanism 23 is provided on the rotating seat 21. The first rotating mechanism 23 can adopt a rotating motor, a rotating cylinder or other rotating driving mechanical device; the driving shaft of the first rotating mechanism 23 is coaxially connected to the rotating column 22, and is used to drive the rotating column 22 to rotate around its own central axis.

[0025] Preferably, Figure 1 and Figure 3 As shown, the fixture also includes a rotating frame 3, on which a second rotating mechanism 31 is provided. The second rotating mechanism 31 can adopt a rotating motor, a rotating cylinder or other rotating driving mechanical device; the driving shaft of the second rotating mechanism 31 is arranged parallel to the carrier plate 1 and is connected to a rotating block 32. Specifically, the driving shaft of the second rotating mechanism 31 is arranged parallel to the placement surface of the clamping fixture; the upper end of the rotating block 32 is connected to a carrier plate 33, on which a driving gear 34 and a driven gear 35 that mesh with each other are rotatably connected, and the driving gear 34 is coaxially connected to the bearing plate 1. The carrier plate 1 and the carrier plate 33 are provided with a third rotating mechanism 36, and the third rotating mechanism 36 can adopt a rotating motor, a rotating cylinder or other rotating driving mechanical device; the driving shaft of the third rotating mechanism 36 is coaxially connected to the driven gear 35, the second rotating mechanism 31 is used to adjust the angle of the carrier plate 1 through the rotating block 32, and the third rotating mechanism 36 is used to drive the carrier plate 1 to rotate around its own central axis through the engagement of the driving gear and the driven gear, thereby adjusting the position of the clamping mechanism 2, so as to avoid the position of the clamping mechanism 2 affecting the contact between the processing machinery and the cylindrical precision parts.

Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
